.To a/ZZ whom it may concern:

Be it known that I, DANIEL DELEHANTY, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented a new and useful Dump'- ing-Scow, of which the following is aspecilia cation. .Y

My invention relates to improvements in dumping-scows in which twoparallel pontons support a garbage or refuse receptacle divided intocompartments fitted with bottom doors; and the objects of myimprovements are, rst, to construct such a dumping-scow as will whendischarged of its load rise sufficiently in the water to insure aclearancespace between the bottom of the refuse-receptacles and thesurface of the water for the purpose of frceing'the receptacles of thetloatable mass; second, to insure the deposit of the contents of thereceptacles when the bottom doors are opened; third, to obtain goodmaneuvering qualities for the dumping-scow. I attain these objects,first, by constructing the scow with two parallel pontons of greatbuoyancy, of any section, preferably circular, at such a distance apartas will allow the load to be discharged from the receptacles which areconstructed on these pontons, and secured by proper framing; second, bymaking the bottoms of the receptacles wider than the tops; third, byforming the rear ends of these two pontons into a ship-shaped stern withtwo stern-posts, each fitted with a screwpropeller, the engines to beplaced in the after ends of the pontons.

I make use of the usual methods for opening and closing the bottom doorsand for propellin g the scow.

In the accompanying drawings, Figure 1 is a longitudinal section of myscow without showing the worm-wheel gearing-shaft and chains. Fig. 2 isplan of same without wormwheel gearing-shaft and chains. Fig. 3 is astern view and Fig. 4 is a bow view without showing worm-wheel andshaft. Fig. 5 is a crosssection through any receptacle on a largerscale. Fig. 6 is a part plan on a larger scale, showing worm wheelgear-shaft and chains.

Similar letters refer to similar parts throughout the several views.

a a a designate the receptacles, which are made wider at the bottom thanat the top, so`

constructed as to form one body with the deck e e and pontons d d.

b represents the boiler for the engines m m. (Shown in Fig. 2 only).

c is coal-compartment.

H is the boilerihouse.

f represents the bridge.

represents the tiller which controls both rudders, as shown in plan,Fig. 2.

g gare strengthening-braces.

7c le lc represent the bottom doors of the receptacles and are above thewater-lineB when the scow is light. i These bottom doors are opened andclosed by means of the chains s s, (shown in Figs. 5 and 6,) whichchains are worked by the longitudinal shaft p, which has bearings on allthe bulk-heads between the receptacles. The shaft p is made to revolveby means of the worm-wheel w and the worm w', the whole being worked bya donkey-engine, (not shown,) which turns the worm w by means of thepulley o.

YJ .I represent the hinges upon which the bottom doors turn. y

A A indicate the water-level when the scow is loaded, and B B the water-level when empty. Y

- My scows may be made of metal, wood, or other material.

What I claim, and desire to secure by Let-l l. In a dumping scow thecombination of two pontons, a superstructure for carrying refusesupported by said pontons and consisting of receptacles having straight,unobstructed sides slanting from the top downward and outward, the saidpontons supporting said receptacles entirely above the water when notloaded substantially as. described.

2. In a dumping scow the combination of two pontons, a refuse receptaclehaving straight unobstructed sides slanting from the top down andoutward carried thereby and having discharge openings between the saidpontons and two screw propellers, one carried by each of said pontons,said refuse receptacle being supported entirely above the water when notloaded substantially as described.
